本发明揭示一种坚固扳手(10)，该坚固扳手(10)包括：一环套筒(36)，其用于接收一螺帽或一螺栓头(NBH，NBH’)；一长形主体(20)，其用于接收来自一块体之击打以将扭矩传递至该环套筒；及一免工具锁紧机构(22、24、26、26’、28、30)，其用于将一螺帽或一螺栓头保持于该环套筒中。该锁紧机构包括：一滑件(22)，其可经操作以接合该环套筒中之一螺帽或一螺栓头；一通道(24)，其用于引导该滑件朝向及远离该环套筒之移动；及一致动器(30，74)，其可经手动操作以相对于该环套筒移动该滑件。该通道(24)经由该环套筒之一内周边(40)通向至该环套筒(36)中。该锁紧机构包括一弹性部件(34)，其朝向该环套筒(36)中之一螺帽或一螺栓头(NBH，NBH’)使该滑件(22)偏向。; an elongate body (20) for receiving blows from a mass to transmit torque to the ring socket; and a tool-free locking mechanism (22, 24, 26, 26', 28, 30) for retaining a nut or a bolt head in the ring socket. The locking mechanism comprises: a slider (22) operable to engage a nut or a bolt head in the ring socket; a channel (24) for guiding movement of the slider towards and away from the ring socket; and an actuator (30, 74) manually operable to move the slider with respect to the ring socket. The channel (24) opens into the ring socket (36) via an internal periphery (40) of the ring socket. The locking mechanism comprises a resilient member (34) biasing the slider (22) towards a nut or a bolt head (NBH, NBH') in the ring socket (36). |
